Left cow abomasum displacement replacer with suture passage

Abstract

The invention discloses a left cow abomasum displacement replacer with a suture passage. The left cow abomasum displacement comprises a replacement needle launcher and a replacement needle with a suture binding hole, the outer edge of the replacement needle launcher is smooth, the replacement needle is a straight needle, the rear end of the replacement needle is disposed in a launching portion, the rest parts of the replacement needle are located in a launching tube, the suture binding hole is located in a needle body located in the launching tube, and the suture passage is formed in a tube body of the launching tube. The launching portion comprises a force-accumulating spring, a hitting head, a connecting block and a buffer spring, and the rear end of the replacement needle is inserted into the connecting block and matched with the same in a frictional manner. By the left cow abomasum displacement replacer, two-side incisions by a greater omentum fixation method can be simplified to one-side incisions, a surgeon is helped to easily feed a fixation suture to an ideal target location on the abdominal wall on the right side, and survival probability of cows suffering from serious diseases is effectively increased; besides, the replacement needle can be protected effectively, accidents that viscera are stung by the replacement needle are decreased, and surgery efficiency and safety coefficient are improved greatly; since the suture passage is arranged, launching success rate of a surgical replacement device is effectively increased.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a surgical instrument for treating the left displacement of the bovine abomasum, specifically, a left displacement reseter for the bovine abomasum with a suture path. Background technique [0002] Cattle abomasum displacement refers to an internal medical disease in which the normal anatomical position of the abomasum changes, leading to digestive system dysfunction. According to the position of abomasum displacement, it can be divided into left abomasum displacement and abomasum right displacement. Since the first report of cow abomasum dislocation appeared in 1898, cow abomasum dislocation has been reported all over the world. In recent years, with the development of the national economy, people's demand for milk and dairy products has increased, and the scale of intensive dairy cow breeding in my country has expanded rapidly. Especially after the "melamine" incide...

AI Technical Summary

Problems solved by technology

[0015] However, the standard omentum fixation method with incision in the left hip has its disadvantages during the operation.

[0016] 1. Due to simultaneous incisions on both sides of the abdominal wall, there are many wounds, great tissue damage, easy infection, and slow wound healing, which is a great burden on sick cattle

[0017] 2. When the operator moves the needle and thread to the right abdominal wall in the abdominal cavity, if the cow suddenly moves or shakes, the operator will accidentally drop the needle into the cow's abdomen or pierce the cow's internal organs, which will cause great damage to the cow

[0018] 3. Some cows have very large physiques. During the actual operation, the operator takes off his shirt and puts his entire arm into the cow's abdomen. However, he still cannot reach the target position on the right abdominal wall, so he can only choose the lower right abdominal wall Fixed position, resulting in recurrence of left displacement
